Guy friend forcibly took a bite of my icecream?

I was talking to another guy on my left while eating a chocobar, when he (on my right) held my hand and took a bite of my icecream.

He's not the type to take a bite of someone's food and I felt like he was kind of telling the other guy to back off - if that makes any sense. I don't know, this might be nothing.

I have caught him stare at my lips for a good 3 seconds when I wore lip gloss.
